PowerBold lock, electric strikes, and Electromagnetic Locks are the three major types of electronic locks that can be connected to the Aibase Smart Building door phones. This article starts by giving you a brief introduction to the three types of locks, and briefs you on how to select the door lock, and then teaches you how to connect them to the door phone relay.

Operation Procedure

• Introduction to Door Locks:
  Electronic door lock mainly has following three types:

A. PowerBold Locks:

This lock has two options, it can either be locked with power (NC)or open with power (NO). When it is locked with power , then the lock can be opened when it is open-circuited.

B. Electric Strike:

Likewise, electric strike can be opened when it is short-circuited.

C. Electromagnetic Locks

Electromagnetic Lock is a type of lock which is locked when the power is on , meaning it can be opened when it is open-circuited.

• How to select the door lock
  You can select the door lock based on the following two purposes.

A. Fail-safe: When applying Fail-safe mechanism, the lock stays locked when the power is on ( close- circuited, with current on) and unlocked when it is open-circuited (with current off). Therefore, fail-safe mechanism allows you not to be locked inside when a sudden power cut occurs. All the above three types of door locks are applicable to the Fail-safe application.

B. Fail-secure: When applying Fail-safe mechanism, the lock stays locked when the power is off (open-circuited, with current off) and unlocked when it is short-circuited ( with current on), which means Fail-secure mechanism can keep the door lock stay locked when a sudden power cut occurs. Both the PowerBold Lock and electrical strike are applicable to the Fail-secure application

• How to Wire the Door Lock to Door Phone Relay
  

  As the wiring for all these types of door locks are basically the same, we will take NO door lock as an example for the for demonstration.

  

  Note

  • Select the NC lock for “ Fail-safe” application, while select NO lock for “ Fail-security” application.
  • The power supply to all these locks must be 12 VDC.
